Yes, I think it depends on each person and their personal beliefs, experiences, etc.. There are some things even listed on this thread which, for example, I would never attempt because of my beliefs. But there are other alternatives (also some listed here) which are natural and work well for me. But they may not work for others.
One more thing, and this is not coming from the fibro community, but I thought I'd bring it up.
My doctor always warns against new gimmicks which keep popping up, even some promising fibro patients "cures" and such. While there are some new, good things which can help us, and (rarely) may even appear to 'cure' some of us, there are also 'snake oil salesmen' to beware of.
Though, once in a while, there may be a new muscle cream or something which just might offer some help. Who knows?
(I keep getting interrupted as I type this, so I hope it somewhat makes sense!)
